The Labour MP believes a "revolution in sex education" is needed to counter sexual bullying and a rise in "sexting" fuelled by the proliferation of technology, especially smart phones, reports the BBC.

Speaking to the Fabian Society's Women’s Network, Abbott will urge a "national conversation" on how parents and teachers discuss sex and technology with today's youth.

She will say: "I fear we're seeing the rise of a 'strip-tease' culture in British schools, and British culture, with the British family unit left marginalised.

"It’s a hyper-sexualised British culture in which women are objectified, objectify one another, and are encouraged to objectify themselves; where homophobic bullying is normalised; and young boys’ world view is shaped by hardcore American pornography and other dark corners of the internet.

"We need to talk about how we put families, and not the lowest common denominator of the market, back in control. We’ve got to build a society based on open-minded family values, and not ‘anything goes’ market values."
